Your games can use these services as follows (these links lead to relevant documentation to help you to get started):

Cognito Identity to allow guest access, with an easy and seamless transition to authenticated access via a public login provider such as Amazon, Facebook, Twitter, Google, or any provider that is compatible with OpenID Connect.

Cognito Sync to store user preferences and games state in the Amazon Cognito sync store, to enable a consistent experience across a user’s devices.

S3 to store and retrieve game assets (including images and videos) and other data.

DynamoDB to store and retrieve JSON documents and information identified by a key, with single-digit millisecond latency at any scale.

Mobile Analytics to collect and analyze usage data. You could, for example, use custom events to track the popularity of different features or locations within your game and use the results to tune and optimize game play.
